in reply to Coding superstitions

I always make explicit dereferences, even with AoAs and suchlike:

my $bar = $foo->[0]->[1]->{'two'};

(Although, since I think this actually improves my code's readability, I guess it isn't really a superstition.)

I also use both & and parens when calling functions, even as I am certain in the knowledge that it will bite me in the arse sometime in the misty future:


I also quote hash keys, for consistency.
